Another genetic characteristic makes the stripes of the tiger very pale; white tigers of this type are called snow-white or "pure white". White tigers, Siamese cats, and Himalayan rabbits have enzymes in their fur which react to temperature, causing them to grow darker in the cold. In the Bristol Zoo, a white tiger named Mohini was whiter than ...
Golden tiger in Buffalo Zoo. All golden tabby tigers in captivity seem traceable to a white tiger called Bhim, [3] a white son of a part-white Amur tiger named Tony. Tony is considered to be a common ancestor of all white tigers in North America. Bhim was a carrier of the wide band gene and transmitted this to some of his offspring.
Panthera is a genus within the family Felidae, and one of two extant genera in the subfamily Pantherinae.It contains the largest living members of the cat family. There are five living species: the jaguar, leopard, lion, snow leopard and tiger, as well as a number of extinct species, including the cave lion and American lion.
This subfamily includes the groups commonly known as tiger moths (or tigers), which usually have bright colours, footmen, which are usually much drabber, lichen moths, and wasp moths. Many species have "hairy" caterpillars that are popularly known as woolly bears or woolly worms .
Tigers now occupy less than 7% of the range they used to, and in Kazakhstan, systematic hunting and a reduction of tiger prey saw the big cats declared extinct in the Caspian region in the 1950s.

The snow-white tiger is a morph with extremely faint stripes and a pale sepia-brown ringed tail. White and golden morphs are the result of an autosomal recessive trait with a white locus and a wideband locus, respectively. The snow-white variation is caused by polygenes with both white and wideband loci. [62]
The study reveals that the snow leopard and the tiger are sister species, while the lion, leopard, and jaguar are more closely related to each other. The tiger and snow leopard diverged from the ancestral big cats approximately 3.9 Ma. The tiger then evolved into a unique species towards the end of the Pliocene epoch, approximately 3.2 Ma. The ...
